BIND 9.16.39 Release Notes

Feature Changes

  • libuv support for receiving multiple UDP messages in a single recvmmsg() system call has been tweaked several times between libuv versions 1.35.0 and 1.40.0; the current recommended libuv version is 1.40.0 or higher. New rules are now in effect for running with a different version of libuv than the one used at compilation time. These rules may trigger a fatal error at startup:
    • Building against or running with libuv versions 1.35.0 and 1.36.0 is now a fatal error.
    • Running with libuv version higher than 1.34.2 is now a fatal error when named is built against libuv version 1.34.2 or lower.
    • Running with libuv version higher than 1.39.0 is now a fatal error when named is built against libuv version 1.37.0, 1.38.0, 1.38.1, or 1.39.0.
    This prevents the use of libuv versions that may trigger an assertion failure when receiving multiple UDP messages in a single system call. [GL #3840]

Bug Fixes

  • named could crash with an assertion failure when adding a new zone into the configuration file for a name which was already configured as a member zone for a catalog zone. This has been fixed. [GL #3911]
  • When named starts up, it sends a query for the DNSSEC key for each configured trust anchor to determine whether the key has changed. In some unusual cases, the query might depend on a zone for which the server is itself authoritative, and would have failed if it were sent before the zone was fully loaded. This has now been fixed by delaying the key queries until all zones have finished loading. [GL #3673]

Known Issues

  • There are no new known issues with this release. See above for a list of all known issues affecting this BIND 9 branch.

BIND 9.18.13 Release Notes

New Features

  • RPZ updates are now run on specialized “offload” threads to reduce the amount of time they block query processing on the main networking threads. This increases the responsiveness of named when RPZ updates are being applied after an RPZ zone has been successfully transferred. [GL #3190]

Feature Changes

  • Catalog zone updates are now run on specialized “offload” threads to reduce the amount of time they block query processing on the main networking threads. This increases the responsiveness of named when catalog zone updates are being applied after a catalog zone has been successfully transferred. [GL #3881]
  • libuv support for receiving multiple UDP messages in a single recvmmsg() system call has been tweaked several times between libuv versions 1.35.0 and 1.40.0; the current recommended libuv version is 1.40.0 or higher.
